,Lila/.imei i i y To @Uithof/n t may concern? Y known 'that Liliana* Hinniucri Lnncifgacitizen 'of hev German Empire,l residing at Amerilraonthelilulde,

in the 4.liingdonifot' Saxony, Germany, have invented certain neiv aiidusetul yimprovements in Flier Spinning and TWi'sti/ng. Ma@

chines; and I do hereby vdeclare tli'e tollen'- ing to be a full, clear, and exact description of the inventiomsuch as ivill enableothei's kskilled in thev art to `which it appertains to make and use thesame. My k,invention vrelates to improvements"in flier spinning` and twisting machines and more*particularly to the construction of the tlierspindles ot such inabearings of the chines. f 4 l have foundthat the bearings 'for the spindles on machines `heretofore used have had various objectionable features, Tand the present'invention is intended to overcome n,

' f spindle which consists in the usual manner loft a steel body carrying on its unsupported such objections asl fully as possible.

The present invention has noiv for its object to provide an improved flier spindle ybearing of the most simple construction possible, and which Willnvork in an absolutely 'and The invention consists'substantially in providing` a double bearing casing ot'lniown 'constructioninwhich the inner sleeve that receives the spindle and that is made spherical in the usual manner inthe plane of engagement of the driving cord, is caused.4

to bear .in a movable manner with its hollow spherical base likewise upon a sphere :trk ner ot a steel body carrying on its unsupported cylindrical upper part injaddition to the driving Whirl@ kof the llier and the,

bobbin.

The middle lportion of the spindle is provided ywith a roundedcollar e Working in an enlarged part of the borevot the innersleeve (Z. The ball' z' forms the tootstep bearing for the spindle Z). `The inner Specification of Letters Patent.

sleeve Z isv bulged at its'loottoin which,y

serves as a bearing for the ball z'. The holloivr 'spherical "iioot of tli'elinne'rl sleeve d bears uponaballfg which inits turn bears" l upona convexs'urface le' ofthe bottom' cap ln the 'improved'bearing thev spindle is i therefore no ,longer/mounted directly in the.

fixed bearingsleeve a, but is mounted indi'` rectly in a sleeve 6l, which, in its turn, owing toits bearingI upon a ball, Iallows the spindle to roch freely even when the outer sleeve a should not be inan exactly vertical position or be screwed askeiv into the spindle rail.V

A turtlier modiiicationis shown in Fig. 2. Now according to this second modilica- .tion,r the base of the inner bearing sleeve 'is'inade 'spherical-and the bottom of thev outer bearing casing yis made spherically concave.` alisthe fixed bearing sleeve which is screwed'into the spindle rail, and b1 is the cylindrical upper part, in addition to 'the driving Whirl c?, the flier and the bobbin.

'o 'lifthe inner sleeve dl.

The loiver end of the outer ybearing sleeve?l is also made spherically holloivr,

The centerrotthe radius of curvature is,` situated in the plane yof engagement of the driving cord, while the'center of the radius ot curvature ofthe rounded base g1 is situkated considerably loiver. The :spindle is therefore no longer mounted directly in the .fixed bearing sleeve al, but indirectly in a sleeve Z1 Which has a rounded base that rests upon the correspondingly spherically concave surface /L ofthe lower part Z1 of the bearing casing With a tendency to autokmatically center itself.

lNhile in describing the invention reterence has been made to particular embodif ments thereof, l Wishitto be understood, tiat my invention is not limited to the examples shoivn in the drawings, and that various changes may be made in the construction ot the elements shown in the drawing. rl`lie'invention may also be applied to ring spindles, in'ivhich case both examples give good results.

I claim herein as inyiinvention:

l1. A bearing yfor spindles,`comprising anM outer sleeve having a hollow spherical bottom, an inner sleeve having a'spherical base resting on said bottom sleeve, said inner sieeve being smaller than the opening in A2; n lier spinning and twisting machines, the combination With the spindle, and driving means therefo'r,of`an element,` providing a rotarysupport yfor the spindle, vand -a member supporting said element,l
